Comment (by knarf):

 Erik, you didn't miss the discussion, you only forgot about it because, as
 I just realize, it happened almost two years back, and you actually
 suggested the name of the variable. (Look for mails on Oct 19 2009 on the
 simfactory mailing list, specifically message id
 B7FFFB04-8D83-42B8-A115-754688D27F07 at cct.lsu.edu) Of course, two years are
 a lot of time to change mind.

 So, your suggestion is to set num-threads to whatever the machine database
 sets by default, and let users choose to overwrite this with one of the
 three mechanisms. I personally agree with that, but I can see that this
 might be inconvenient for some users. At the same time, the current
 situation is even more inconvenient for other users (having to remember
 how many threads should be used on a given machine instead of just '1' to
 disable openmp). This is why I agree with you.

 Should we bring this again to the users list, or should we just move
 ahead?
